Research Interests

My main area of research is Clostridium difficile and healthcare-associated infections in older people. Together with a group of collaborators at UCD, the Mater Misericordiae and St Vincent¿s University hospitals, Beaumont hospital and the Health Protection Surveillance Centre (HPSC) our research has focussed on the epidemiology and the human immune response to C. difficile infection. Our work examines the host inflammatory response to C. difficile infection and outcome.  

Our recent research has involved an examination of the faecal microbiome and how it is affected by hospitalisation, diet, medications and frailty in individual patients.

As a member of a sub-committee of the Health Protection Surveillance Centre, I was involved in drawing up National Guidelines for the Surveillance, Diagnosis and Management of C. difficile Infection which were launched in 2008 and revised and published on-line in 2013.  I am also involved in other collaborative research on stroke, atrial fibrillation and medical education.
